If — big if — Apple wants to show off ARKit at WWDC 2017, here's how they could do it!

Come Monday, the WWDC 2017 Keynote will be set in stone. Now, though, I can speculate about anything — including the potential for an augmented reality framework.
"And to show it off, I'd like to welcome onto the stage John Hanke, CEO of Niantic." "Thanks, Craig. Hello, everyone! Now, remember what it used to look like when you were playing Pokémon Go and you caught a Tyranitar in AR mode? Well, with Apple's new augmented reality framework, ARKit, now it looks like THIS!"
No one outside a very small group of people at Apple know for certain what we'll see at the WWDC 2017 keynote taking place this coming Monday. Even then, plans can and do change up until the last possible moment. So why speculate now? Because it's the best possible time. Come Monday afternoon, the myriad lines of dream and expectation will have been canceled out into a few hard facts. Everything will be known. Until then, though, I get to wonder out loud about anything and everything — including augmented reality (AR)
Many of the other tech giants already have AR technology in the field. Google had Glass and Android has a variety of headgear and built-in apps. Microsoft has HoloLens. HTC has Vive. Snapchat has Snapticles — er, Spectacles. Facebook has Oculus and is rolling out more. And the list goes on. Apple, as usual, has been quiet about future plans and projects.
But not completely quiet.
